Welcome to the forums, newcomer!

Gigabyte Aorus Master
Gigabyte is the brand of the board, while Aorus is the series off of which the board comes from, we'll need to know the model of the board.

The picture isn't clear enough but I'm guessing it says CPU, meaning there's a fault with the CPU or the pins in your motherboard's CPU socket are either bent, broken or you have too much force mounting the cooler.

13900k cpu
It could also mean you have the dreaded CPU degradation issue on 13th Gen intel processors.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I did cmos with the button at the back and with screwdriver. Did also the q flash plus thing.

More details: My external sound card doesn't show any lights on as usual when I turn on the computer, nor does the keyboard.
 
In the gigabyte manual it’s looks like it’s CPU - look at the pics and tell me if I’m right please.

Weak forum ever?
No magic answers read the 3rd post. It's the first things to check if you have everything hooked up properly, remember we're not at your house looking at it.

If your saying what I think you are don't try to use that!

Remove all drives, video card everything.
You should only the the power supply, 1 stick of memory, CPU and cooler. Monitor hooked up to motherboard. Try to boot to BIOS.

No boot then remove the CPU get a magnifying glass or something and check for Bent pins in the motherboard

Probably meaning Fractal Design Torrent.

I'm not a tech guy, all I want to know is if the processor is dead - so I can take it apart and take it to the store. I have another 14 month warranty on it. I have a warranty on all the components in this pc. I just want to understand what's dead here, which part I'll take (I bought different parts from different stores). I don't have the ability to start experimenting right now, unfortunately. I’m a noob for that.

You can't say for sure that it's the cpu that's broken even though the light of the “cpu problem” is the one that's on on the motherboard?

Did the system work normally before?
What did you do before it didn't work anymore?
Were you overclocking cpu or gpu?

Remove graphics card physically from system.
Connect monitor to integrated graphics video output on motherboard.
Try to boot your system.

I removed the 4090 and tried connecting a monitor directly to the motherboard - didn't work, then I tried connecting another monitor - same result, both didn't turn on. Exactly the same result.

From the first week I had it with me I got blue screens every now and then, not even during strenuous work (just surfing the internet). I installed maybe 3-4 times Windows 11 after formatting and I still got blue screens every few days. About a year ago I tried to experiment with OC for the processor, but it was only in the experimental area 5-7 times and I stopped. I realized that with the fans I couldn't get any advantage. In the last year without any OC the system worked - every few days and sometimes several times a day blue screens.

The morning the system stopped working there was no strenuous work - just surfing the internet and YouTube.

Can we say with a high percentage that it's the processor? And does the fact that I experimented a little with OC a year ago put my warranty at risk?

13th and 14th gen cpus have a deterioration fault.
It has to be fixed with BIOS update to prevent permanent damage.

If you were running your cpu without necessary BIOS updates and in OC mode,
this may have killed it.

I updated like a clock all bios updates with the gigabyte app - and I wasn't really hardcore oc it, just testing with the intel app to see what I can get. The cpu looks like new, no burn or something visual on it
